The fantasy sequence with the Muppets as babies was so popular, it resulted in the successful cartoon spinoff [Muppet Babies].

Rizzo the Rat appeared throughout the final season of [The Muppet Show] and along with Scooter as the Happiness Hotel bellhops in The Great Muppet Caper, but this is his first major role with the Muppets and his first appearance with his more-"wiseguy" personality.
